TUCSON, Ariz. – The desert sky glows soft orange before sunrise, and the Catalina Mountains cut sharp shadows over the valley. A faint, warm breeze drifts through neighborhoods as Tucson wakes to another classic desert Halloween — crisp in the early morning, bright and hot by afternoon.
The National Weather Service in Tucson expects sunny skies and highs near 88°F through the Halloween weekend, continuing a stretch of warm, dry weather. Trick-or-treaters can expect pleasant evening conditions, with temperatures near 70°F by early dusk and dipping into the mid-60s as festivities wrap up. For those traveling along I-10 or heading out to Halloween events across Pima County, visibility and road conditions will remain ideal.
Saturday and Sunday stay nearly identical — clear, calm, and hot for late October. Highs climb toward 90°F by Sunday, roughly ten degrees above average for this time of year. Winds will stay light, shifting gently northwest each afternoon before calming after sunset.
By early next week, models show a brief heat spike with highs possibly reaching the low 90s Monday and Tuesday — an unusually warm start to November even for the Sonoran Desert. No rain is expected, and humidity remains low, extending the fire-weather risk for rural areas west and south of the metro.
Residents should plan for extended warmth and keep hydration in mind during outdoor Halloween activities. Cooler mornings return later next week, but for now, Tucson remains locked under clear skies, hot days, and perfect desert evenings — a golden stretch to end October and begin November.
